CROSS-REFERENCE TO RELATED APPLICATIONS

This is a continuation application of PCT/EP03/01204, filed Feb. 7,2003, which is incorporated herein by reference in its entirety, andalso claims the benefit of German Priority Application No. 102 05 190.9,filed Feb. 8, 2002.

FIELD OF THE INVENTION

The present invention relates to cosmetic or dermatological formulationscomprising one or more polyols in a concentration of 0.1 to 20% byweight, one or more diols from the group consisting of2-methyl-1,3-propanediol, pentanediol, hexanediol in a concentration of0.1 to 25% by weight, in each case based on the total weight of theformulation, and the use thereof.

BACKGROUND OF THE INVENTION

The skin is the largest organ of humans. Its many functions (for examplefor regulation of heat and as a sense organ) include the barrierfunction, which prevents the skin (and therefore in the end the entireorganism) from drying out, certainly the most important. At the sametime, the skin acts as a protective device against penetration anduptake of substances from the outside. This barrier function is effectedthrough the epidermis, which as the outermost layer forms the actualprotective covering against the environment. With about one tenth of thetotal thickness, at the same time it is the thinnest layer of the skin.

The task of cosmetic skin care is to strengthen or re-establish thenatural function of the skin as a barrier against environmentalinfluences (for example dirt, chemicals, microorganisms) and against theloss of endogenous substances (for example water, natural fats,electrolytes).

The aim of skin care is furthermore to compensate for the loss of fatsby the skin caused by daily washing. This is important precisely if thenatural capacity for regeneration is not sufficient.

A central task of skin care is moisturizing of the skin. The moisturecontent of the skin has an important influence on its appearance and itsstate of health: the higher the water loss, the rougher and more friablethe skin becomes. Its elasticity and plasticity decrease, and itsintactness is no longer guaranteed. To moisturize the skin, moisturizingsubstances (moisturizers) which assist the water-binding capacity of thehorny layer are added to cosmetic and dermatological formulations.Conventional skin moisturizers, which are employed in almost allcosmetic and dermatological formulations, include the polyols, such asglycerol and sorbitol. In addition, other compounds are also employed,such as ethoxylated polyols and hydrolyzed proteins. Components of thenatural moisturizing factor of the skin (NMF), for example urea andcertain amino acids, are moreover used.

A great disadvantage of the prior art is the adverse sensory propertiesof cosmetic or dermatological formulations which comprisepolyol-containing moisturizing agents. As a rule, these feel tacky andgreasy on the skin and make the corresponding products unattractive tothe consumer. To suppress these negative properties, expensive siliconeoils and lipids, which increase the preparation costs of thecosmetic/dermatological compositions, must be added the formulations.

SUMMARY OF THE INVENTION

It was therefore the object of the present invention to eliminate thisdisadvantage of the prior art and to develop inexpensive cosmetic ordermatological formulations with significantly improved sensoryproperties. In particular, the formulations should not feel tacky. Thecontent of silicone oils and other lipids which reduce the tackinessshould be reduced.

Cosmetic and dermatological formulations are employed and consumed byconsumers worldwide in the most diverse climate zones. Since thedevelopment of cosmetics or dermatological agents is quite involved andexpensive, attempts are increasingly being made to develop recipes whichcan be employed globally under the most diverse climate conditions.However, the heat stability of these highly complex metastable mixturesis relatively limited. At low temperatures of below 5° C. theirviscosity increases so severely that the formulations can scarcely stillbe used or processed. The products also tend towards separating out ofwater and phase separation at low temperatures and with relatively widevariations in temperature, such as may occur, for example, duringtransportation.

It was therefore a further object of the present invention to developheat-stable cosmetic and dermatological formulations which, because oftheir low viscosity, can also still be used and processed at lowtemperatures. Surprisingly, these objects are achieved by cosmetic ordermatological formulations comprising

-   -   a) one or more polyols in a concentration of 0.1 to 20% by        weight,    -   b) one or more diols from the group consisting of        2-methyl-1,3-propanediol, pentanediol, hexanediol in a        concentration of 0.1 to 25% by weight,        in each case based on the total weight of the formulation.

The formulations according to the invention are distinguished by a highheat stability and low viscosity at low temperatures. Furthermore, theyhave excellent sensory properties, such as a low feeling of tackiness onthe skin.
